Twelfth Quarterly Report for Small Scale Field Test.
Third Quarter Report, 2014 online (20th Report).
This quarterly report is the last, prior to submitting the final report. All of the tasks and subtasks are listed herein with dialog pertaining to activities conducted in this last quarter.
Type logs are being checked for completeness prior to final release.
Affirming possible and previously unrecognized faults has been made easier with the increase in seismic activity in south-central Kanas. The DOE-CO2 mapper has is updated to include the earthquake events since 2011 that are focused around the Mississippian Lime horizontal drilling play. Large volumes of brine are disposed in and around this play extending from north-central Oklahoma into Kansas. Increased seismicity has followed this trend.
The increased in both cumulative brine disposal with some injection wells permitted at high rates (20,000 to 40,000 bbls/day) but lacking daily injection rates and pressures is problematic to understanding or modeling the role of injection and the seismicity or, important to this project, of considering the circumstances in the context of CO2 disposal that has been evaluated in this area. Accordingly, we have elevated the risk of injection of large volumes of fluids pending ongoing analysis outside of this funded program. The fact that the extensive subsurface and surface lineament database exists for the area will be critical to further assessment that will included geomodeling and simulation.
